I have a 1978 Honda Hobbit that started to run crappy and my preliminary investigation points to a weak yellow spark. Where do I begin diagnosing the problem. Thanks Jack
I picked up a barn find Hobbit with 6000+ miles on the odometer and a compression reading in the low 70’s. I have not attempted to start it because it has too many other issues but I was wondering is it worthwhile to have the cylinder rebored and install oversized rings OR purchase a new jug, rings and head?Your collective thoughts please. Jack
I am Setting the timing on my Hobbit and the timing light is lighting up half way between the F and T marks. To get it to fire at the F mark do I open or close the points.? Thanks Jack.
Is there a minimum cranking speed (motor rpm) that a moped needs to turn in order to produce a spark. This question comes from a Hobbit PA50II motor that refuses to run smoothly and I think I traced the problem to a timing issue. I hooked up an induction timing light to the motor and cranked over very slowly to see when the light blinked. To my surprise I needed to really increase the speed to get
I have 3 Dewalt cordless drills of various sizes and vintages and the clutch/transmissions are slipping on all of them. Does anyone have any experience in repairing them and is it worth the effort or just chuck them and get new ones. Thanks in advance. Jack
Does anyone have a recommended for a flywheel holder for a Hobbit. My DIY model made from bolts, nuts and a wooden handle finally gave out. I know Treats has several types but the person I emailed could not guarantee any would work on a Hobbit. Thanks Jack
Still trying to get the timing right on a Hobbit. In order to have the spark fire at the “F” Mark on the flywheel I had to close the point gap down to .010 of an inch. The problem is the motor still runs like the timing is off. Any suggestions. Jack
Stephen: I picked up another basket case Hobbit PA50II without a carb and several other parts. I have several PA50 II reeds and reed block in my parts pile and was just trying to make the bike stock. I am sure someone out there has a carb they are willing to part with. Thanks Jack
I tried drilling out a PA50I, but I do not think it is working. So anyone have a Keihin PA50II carb for sale please let me know. Thanks Jack
This is very old metal timing light that does not have an inductive connection. There is a short coil spring that hooks on the end of the spark plug and the other end goes to a alligator clip on the end of the HT wire of the light.
I just finished a stock rebuild of a PA50I and was checking the timing when I received a shock while holding the timing light and touching the engine. What if anything did I do wrong? Thanks everyone. Jack
A basic Hobbit timing question. I set the point gap exactly .014. But it is still running rough so I used a timing light which shows it actually firing before the correct fire position. “The fire mark on the flywheel is to the left of the mark on the engine case when running” Do I open or close the point gap? Thanks Jack.
Hello everyone:I am not sure were to put this, so it I put in under GeneralDiscussion. When I use Google to open the Moped Army web site I see the usual title page. However when I click on one of the sub topics like “Repairs”, I get a pop up advertisement. I can then close the ad and view the forum as normal. This only happens when I first log onto the web site. Can one of you computer gurus
Papa.Thanks for the response. Yes I have a press and all type of precision measuring equipment. i do not understand all the details you were discussing but I will figure it out. My first attempt will be to get it apart and see if Treats has replacement parts.Jack
A hypothetical question! Is it possible or even worthwhile for the average person to disassemble a moped crankshaft and replace the connecting rod and or bearing? And If it is possible, how would you do it? I have several worn cranks in my parts pile that I would like to experiment with. Any suggestions would be appreciated. Thanks. Jack
My vote is for The Princess Bride, great lines, laughs and cast. And the entire family can watch it. Jack
The Answer Is: I stand corrected and humbled. I removed the rectifier from the ignition circuit and stated the motor. It ran, no questions asked.I put a call into Shaun Myron at Myron Mopeds (knowledge guy) who said the rectifier was installed to bleed off current from the ignition circuit to give more power to the lights. I briefly looked at the wiring diagram and can not understand how that woul
Hello JBOT:I disagree with your comment about the need for a rectifier. However I will do a test tomorrow and let you know the results. The reason I disagree is that the b/w wire from the power coil on the stator (which produces AC current) run directly to the rectifier and then to the a high tension coil. The rectifier convert the AC to pulsating DC. The other two wires wires run directly to the
Dr. Marc:Yes I am looking for the rectifier that converts the AC voltage to pulsating DC voltage. I need this one for a test stand I constructed to run my motors before I go to the effort of installing them on the bike. I will send you a photo if you are interested. I have pay pay, credit card and even cash. Please tell me what your asking price is for the rectifier. Remember: “Better is the en
Purchased a used Honda Hobbit rectifier from Shaun at Myron’s Mopeds for $16.00.Jack
Yes I looked on eBay .Nothing there.
I am in need of a rectifier for a Hobbit. I posted on MA buy/sell and no one has one and Treats & Dos Cycles do not have one either. Does anyone know of another source or a reasonably priced after market unit that will work on the Hobbit. Thanks. Jack
Picked up a junk Hobbit to day and the rectifier is missing. Anyone have on for sale.Thanks. Jack
Thank you very much. Jack
Hello on a rainy day in Connecticut:All I ever work on are Honda Hobbits. Going through my pile of misc parts I found these two rubber gaskets. I have no idea what they are for and worst what did I forget to install. All the repair parts I ever purchase is from Treats if that is of any use. The gaskets look to be 5/8” wide, 1 1/8” long and about 1/8” thick. Thanks everyone.Jack
Happy Thanksgiving everyone. One of my Hobbits started running very poorly and then I noticed lots of sparking from the points. What is the cause of this and what can I do to fix it? Thanks Jack
Rebuilding the carburetor on another Hobbit PA50I to night and just installed a new number 60 jet. Just got to thinking, what does the “60” stand for? It is a measurement of what? Can someone enlighten me.Thanks Jack
What is the best way to ensure a good air tight seal between the reed block and the motor on a Hobbit. The PA50 parts diagram (as far as I can tell) does not show any gasket but treats has two varieties for sale. Just curious as what is everyone uses. Thanks Jack
