2 cycle engine help?

Question

i have a craftsman weedwacker 32cc engine mounted on a gas scooter it will only run at full choke and only for 4 to 45 seconds then i have to re-prime it every time its mounted on its side if tat makes a difference

tank is mounted above the motor (not upsidedown or sideways

Answer 1

I would start thinking about your jets ( if any ) and how much gas is getting into the combustion chamber. If it dies out, and you gotta re-prime to get it started then the engine is starving. All Priming does is add fuel directly as does a choke. Also it is kinda hard to figure out where any problem could be without looking at how the fuel feeds. I'd start there honestly

Answer 2

Check the little breather hole in the gas cap! Sometimes a little bug decides to lay an egg in that hole, and if he does, you'll get the same thing as you describe! I repair mowers, etc., with the small engines, and the problem crops up frequently, especially if the machine is stored, or not used a lot. A small piece of wire poked thru the hole will suffice. Just remember to take out the wire before starting it. On a 2 cycle engine, it makes no difference as to which way the engine is mounted.
The deal is this: You try to start it--it runs for 10-15 seconds, then quits. So, you decide to check the fuel supply, and remove the gas cap. This allows air to get into the tank, breaking the vacuum, and it will then start, until the fuel goes out into the carb., and the vacuum forms again! So, you remove the cap and---aren't we back at the first place again???

Answer 3

confident and No... maximum cutting-edge 2-strokes (not 2 cylinders as stated above, 2-strokes could have any style of cylinders) are fed by potential of carburators. by using character of the two-stroke beast, they allure to greater gas than they are able to apply, and a few of that gas passes rapidly via to the exhaust with out ever burning. have been somebody prepared to dedicate the components necessary to develope a stable, working direct injection EFI device, then they does not could be so undesirable. Bimota certainly did this with the V-Due 500, however the gas injection device had quite some flaws out of the production unit. however, it exceeded EPA regulations and grew to become into legal in 40 9 states (California being the exception, continually the atypical state out). So this is completed. yet another exciting actuality is that Detroit Diesel engines (semi-vans) run 2-stroke Diesel autos and turn tens of millions of miles on the roads in this us of a each and each twelve months. So it is not that anybody's attempting to do away with 2-strokes, this is in basic terms that they are quite annoying to freshen as much as meet ever tightening emissions regulations ~ 4-strokes are plenty easier in that regard.

Answer 4

Might have low compression and need a top end rebuild (cylinder, piston & rings).
Just enough compression to run, with a supper rich volitile mixture.
The strain of trying to move a scooter will ware out the engine faster than normal useage.

Answer 5

If the fuel tank is also inverted, this could be the problem.

Answer 6

wow these people have no idea what they are doing!
check your gas oil mix.
clean your carb

Answer 7

clean air filter
