Thanks Jimbob, the thing is I was using the guides on this site: http://www.mopedarmy.com/wiki/Ignition_timing_for_pointsand this print out: http://www.mopedarmy.com/mediawiki/images/8/84/Puch_timing_sheet_5in_wheel.pdfI used the timing for a random puch kit.It's not that I feel like "I don't have to buy" its that I cant right now due to financial constraints.
Phew okay, first of all thanks for the help. Now I spaced the cylinder like you said in the previous discussions. I had the gap set right like you said before but it wouldnt run so I set it at .040, guess I will set it back. I cant afford anything more than a clone bing right now. Let me repeat, I have been listening to you guys. When it comes to doing the procedures right, sometimes it comes down
Actually that compression reading is probably inaccurate. I read that using an extension will cause the psi to be lower than it actually is. I can't use it without the extension.
Point gap set at .040 inches.Timing is set at 1.44 mm BTDC, around 19 degreesThe max head temp that I recorded was around 290 FCompression is 110 PSIBing is a clone, atomizer is a 2.17
The arrow is pointing towards the exhaust port. That is correct right?
I should also add that the kit is a k star 45mm with an o ring hi compression head and a 15mm bing carb
The exhaust pipe is not clogged as it is a newer proma circuit. The needle is in the leanest position, I tried to move the needle to a richer position and it made it worse. The Jet is a 77. When the exhaust is off it fires right up. With it on it barely even fires.
Since the flywheel is connected directly to the Crankshaft no clutch is necessary. Just pull on the rope and it will start up.
Nice observation, I will try that. At the moment it wont idle unless it is screwed in that much. I am pretty sure I need to down jet as well. I have an 82 jet with a 70cc k star.
Here are some more pictures
So I decided to add a pull start so my wife could start the moped easier due to the high compression making pedal start hard.These are the components I used:I ordered the pull start from Ebay: http://www.ebay.com/itm/370963188602?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AITThis is what is used to Connect the pull start to the flywheel: https://www.treatland.tv/ProductDetails.asp?
So I got a new cylinder and piston. Chamfered the ports, matched the exhaust and intake ports. Took a golf ball and tennis ball and hemi'd the head a bit. made sure the rings were gapped properly not exposed to the exhaust. Decked the cylinder a bit. Lost some low end power but top end seems a bit better. IT seems to bog a bit when I give it some throttle from a slower speed. IT has a 82 jet
Nice encouragement for a newbie. I think the solution here is clearly a chainsaw clutch.
Oh and I did replace everything in the bottom end and installed it correctly but that's besides the point seeing as the problem has been found lol.
So I took the head and cylinder off and the ring was broken in half *sigh* So I will have to space it correctly next time. Wish I would have known this, doesn't mention it (unless I missed it) in the k-star compendium article in the wiki which I followed including the correct ring gapping and timing.When I get a new ring should I have the cylinder decked after I space the base gasket correctl
I am running a 50:1 ratio. Seems like that was what most people were saying to run.
I timed it according to specs recommended with the k star with a micrometer. I said I think because I can't remember what the exact degrees were but they are correct. I will check the exhaust port clearance.
Well all of the top and bottom end are brand new with the needle bearing in the piston and a alu stuffed crank. It is crazy hard sometimes to pedal and other times not bad at all. Seems like it is binding up randomly. Wonder if it has to do with me not making sure the exhaust port is wide open? When it runs it runs great and doesn't seize or anything. Seems like starting it is hardest after i
It starts if with a drill btw.
I'm running points which are new, I timed it according to what they said k star should be, I think 17 degrees. The crank is alu stuffed. It is physically hard to pedal start so I am guessing the comp is too high? It is possible for engine to soft seize while trying to pedal start because sometimes it just won't crank, I bent a cotter pin in the pedal one time Lol
Wow did not know that. I thought I had seen something like that in an earlier post but did not know if it applied to k-star. So add a thicker base gasket then? Are you talking about the o-ring or the piston ring? Thanks for the help.
Meant to say pain in the ass. Stupid auto correct.
Put a 70cc kstar head on my maxi with a hi hi comp head. The power is great but it is a pain in the assignment to start it. Is it recommended to lower the compression on these heads? If so should be done by dremel or just adding a thicker head gasket? Thanks
Do treats or 77 or somebody else sell these or do I need to find a new one? I looked on treats and 77 but wasn't sure whether the ones I was looking at were correct or most of them were plastic.
Okay will check, I know when I replaced the crank I had to take one of the washers out of the plate or else it was grabbing constantly.
Hi all, after installing a hi comp head from treats my e50 motor is a little hard to turn over naturally. When engaging the clutch to start it is a bit hard for my wife to pedal and half the time the clutch plate just slips. Is there a way to make the contact between the plate and clutch material better? There is plenty of starter clutch material on the clutch itself. I have adjusted the cable so
The wire was a bit expensive, can I just unhook the ground to gain the voltage back?
I'm using a NGK B6HS plug, is that a non resistor plug?
What spark plug cap or gap? I gapped accoring to the the manual at .018, I am using an NGK B6HS spark plug. The coil is this: https://www.treatland.tv/moped-external-ignition-coil-p/moped-external-coil-red.htmAnd the condensor is an external one made for a 60's VW bug
So I got one of those atomic shielded spark plug plug cables (the one with the ground wire attached to it) After installing it my moped is hard to start than before. What would be the cause of this? I am supposed to connected the ground wire to the frame right?
