JDcrawlers Messageboard

yellowcrawler, thanks for the post. The link you gave leads to the carb manual that I downloaded and printed when I started working on this problem. At this point I'm willing to try anything so later today I'm going to try sealing the venture and see if that helps. To recap, the compression is good ...

I can back out the load needle until it is ready to fall out and still have to run it with choke under load.

Thanks for the input again, Lavoy. I've already done what you just suggested - all passages will flow brake clean through them and the holes in the nozzle are open and clear. Just tried a different coil but there was no change. Have you heard about the venture having to be sealed with some kind of s...

Yellowcrawler, the venture is removable. What type of sealer are you talking about? B Town, all of the correct parts are there. Compression is good and there are no vacuum leaks. I'm going to try another coil today to see if that makes any difference. Thanks to everyone for their replies.

Yes, I have completely disassembled it several times. That is what I'm thinking, something is plugged somewhere but I just can't see it or find it.

I was wondering about an ignition problem. I have cleaned and set the points, but do you think a coil going south could cause these symptoms? It has new plugs.

Have not checked compression. I don't think that is the problem because it idles so well. If the compression was low I would think the idle would not be as good as it is. I will check it just to be sure.

And the governor is working as it should.

Air cleaner is hooked up, clean and functioning properly. I've taken apart the carb several times and blew out every passage in it. Thanks for the replies but so far everything mentioned has been checked or done.

Thanks, but I've checked that. Even pulled the fuel inlet elbow off of the carb to check the strainer - clean as a whistle. No additional filter in line. It's definetly something in the carb ( I think ). Open to other suggestions.

Hoping someone can shed some light on my problem. Recently bought an older 440 crawler and the guy I bought it from said it has had a carb problem for years - namely it will only run with any kind of power if you keep it on at least 1/2 choke. Since I'm a retired auto mechanic with a lot of carb exp...
