Re: Hobbit PA50II problems HELP!!!!!!

oh i forgot to mention i cleaned the points and was going to replace them...could this be the issue?? please help thanks again

Re: Hobbit PA50II problems HELP!!!!!!

Fuel to air mix is probably off. Sounds like it is flooding, maybe try cleaning your air intake?

Re: Hobbit PA50II problems HELP!!!!!!

i did clean that too...should i up jet? or do i have to mess wit the carb??

Re: Hobbit PA50II problems HELP!!!!!!

if your tank was all rusty your carb is probably pretty nasty as well, take it off using the way described on the wiki and tell us what happens

Re: Hobbit PA50II problems HELP!!!!!!

No mention of a fuel filter - did you add one?

Re: Hobbit PA50II problems HELP!!!!!!

Actually- The problems you are having sound a lot like the problems my buddy had when he recently improperly cleaned his puegots tank. You probably still have water in that thing. Flush It! Dry It! Flush It!

Re: Hobbit PA50II problems HELP!!!!!!

yea I took off carb completley cleaned it out..I'm pretty sure all water is out...it was like a month ago...fuel filter I have to add one? And than why would my girlriends brothers run better than wit stock exhaust?

Re: Hobbit PA50II problems HELP!!!!!!

BUMP!!!

Re: Hobbit PA50II problems HELP!!!!!!

an in-line fuel filter is like a safety net for all those little pieces of rust that managed to get through the petcock filters. So yeah, take off the petcock and check that filter that runs into the tank and the one below the on/off/res. switch on the petcock. Then, goto your local car/lawn mower part store and pick an in-line fuel filter. Its better if its clear so you can see if any debris is adding up. Also, take your old fuel line to the store and buy some new (of the same size!) and match the in-line fuel filter properly to your stock fuel line size.

In a nutshell, an in-line fuel filter will not make you go faster.

Re: Hobbit PA50II problems HELP!!!!!!

Dude you MUST have an inline fuel filter for that thing. You will be cleaning your carb every 4 days if you don't. If that tank was that bad, you better get a filter. They are like 5 bucks at any auto parts or hardware store. Clean the carb. I bet it will run nice again.

Re: Hobbit PA50II problems HELP!!!!!!

"he took my stock exhaust and sawed off the pipe before the box"

"And than why would my girlriends brothers run better than wit stock exhaust?"

That's just it he aint running stock. Mufflers act as restrictors so his is fully unrestricted. I hope he up jetted because he'll be in for a surprise if he takes any long trips.

As for your problem, you say the plug is getting black which would mean a rich condition and yes that would slow you down. My advice go to your Honda dealer and order a 78, 80, 82, 84 jet and start experimenting with plug chops until you get the best speed with a normal read on your plug. Also, you may want to consider synthetic 2 stroke oil and then you can use anywhere from a 50:1 mixture to the factory 25:1 without worrying about too much or a seize.

I run LeoVince with an 80 jet everything else stock and have no problems. I also switched to the synthetic oil and prefer the burn and the extra lubricating factors it affords.

Re: Hobbit PA50II problems HELP!!!!!!

thanks guys ...im gonna take fuel line off and get a fuel filter....i called the honda dealer and they said i have to bring in my old jet to order new jets....does anyone know wat size it is? well i guess i have to take it off any ways to clean again......and get the synthetic oil...thanks for all the help i hope this makes it run smoother and faster than my girlfriends brothers....

oh and JB wat will happen to hit if he doesnt upjet?? thanks again

Re: Hobbit PA50II problems HELP!!!!!!

*****to his if he

sorry mispelled it lol

Re: Hobbit PA50II problems HELP!!!!!!

Before I got the jetting correct I soft seized 2 x on some long trips running wot at top speed not fun. If this happens repeatedly it will lead to scoring of the cylinder and loss of compression and possible hard seize. You seem to be running rich so you may already have a higher number jet than stock or the previous owner could have drilled it. I'd stick with new jets from the dealer they're cheap, about 6 bucks a piece and you know exactly what size your putting in.

One last thing consider lining your tank. I did it and no ore rust problems. I like KBS coatings, they give you a 3 step kit and it has held up. They're made for motorcycles and you get enough material for two tanks. So if you get together with a buddy you both can do your tanks for the price of one. And put in a in line filter to keep the dirt out.

Re: Hobbit PA50II problems HELP!!!!!!

ok so i bought the fuel filter and new fuel line and ordered jets and decided to change it when jets came in...so i go out and cruise yesterday and i hit a bump and it just stops...and wont start so i swicth spark plug and it runs....like a couple hours later...it just like stops like no power only goin 15mph max...does any one know wat happened now? oh i put in the synthetic oil and my friend said that might have messed it up bcuz its thick? please i need help again lol

Re: Hobbit PA50II problems HELP!!!!!!

JB oh man u think i soft seized mine?? bcuz it doesnt go more than 15mph if that mostly 10mph..im gonna take it all aprt maybe tom and see...how could i tell if i soft seized it??

Re: Hobbit PA50II problems HELP!!!!!!

Did you use synthetic 2 stroke oil because it aint thick. If you want email me direct and I'll try to help you sort everything out.

Re: Hobbit PA50II problems HELP!!!!!!

If you are running- but just running slow- you could have a clogged exhaust port. I had that problem on one of my hobbits when I first picked it up. It wouldn't go past 7 mph because the exhaust port was so fouled with carbonized junk. You might try taking off your exhaust and checking the port, and maybe cleaning out the pipe.
