HD cart won't start
I'm new to the cart world but worked on two strokes in sleds and worked on plenty of cars but this has me stumped. I have a '82 HD and the engine won't start. It verified spark, and have fuel to the carb. The plug isn't getting wet, is there some sort of reed system on these engine that might be stuck? I do get fuel driping back out of the carb when I spin the engine for a while. Tryed a little starting fluid as a last resort and it still won't fire. I checked the compression as suggested on a parts web site and it all looks good. Any suggestions?

First off, welcome to BGW!
I would do as 4X4 CC mentioned. Give the carb a good cleaning. Make sure to use a small wire to ensure the main jet passageway is clear. |

Re: HD cart won't start
I agree with both of these guys and would also try to add alil gas directly to the piston and see if she will fire and I try to always hit the little passage ways and or holes in a carb with some compressed air also.

Re: HD cart won't start
I'll give that a try but way wouldn't it fire spraying starting fluid in the intake then?

Re: HD cart won't start
I totally missed this before... Please please please do not use starting fluid in a 2-stroke engine. It breaks down 2-stroke oil and causes scoring and welded up rings. Use carb cleaner and it never hurts to put a little 2-stroke oil into the cylinder either. It will protect your engine.

Re: HD cart won't start
I think you should remove the spark plug and put a little fuel mixture in the chamber. If it fires some you might have bad crank seals. If it does not fire there may not be a spark at the right time.

Re: HD cart won't start
The reason to put fuel mixture in the chamber is: if there is no crank case vacuum (bad seals or reed valve) the fuel will never get to the combustion chamber, so put some there and find out. Also the Harley Davidson engine runs normally with much less compression than other 2 cycle carts. The compression should read around 80# forward and 85# in reverse, Absolute minimum is close to 60# to 65# maybe 70#. I have had one as high as 90# and I have heard of higher but usually that means an exhaust constriction (stopped up muffler or carbon build up).
A Compression test should be done in forward as well as reverse and with the throttle wide open. |
