1650 issues
 

Hi everyone,
I am new to the forum and have been trying to figure out an issue I am having with my 1650. I bought it last year at an estate sale and at the time just needed the carb rebuild. It ran great all last year and fired up pretty good this spring when i took it out of the shed about a month ago.
Well when i was mowing, the grass and leaves built up in the deck and it locked the blades up and caused it to stall out (I know not smart). Well now it idles a little ok but when i turn the throttle up it spits and sputters and dies on me. I've already changed out the headgasket but that obviously didnt fix the problem. Any help is appreciated!

Welcome to OCC :beerchug:

Do you use any fuel stabilizer or add MMO ( marvel mystery oil ) to your fuel?

Sounds like it may be a fuel issue due to clogged passage ways in the carb. Is your air filter clean?

Fuel system cleaning should be the first order of things with an old tractor.
Learned this the hard way, clean out EVERYTHING and make sure that it is clean, the make sure none of the 'gism' is left in your float bowl then start from there. When I get an old one, I flush the tank, replace the lines, filter etc. and then see what comes up.

I tore apart the carb again thinking maybe that was one of the issues but it was clean as is the gas coming out of the tank. Ive adjusted the carb every which way too.

Sorry i also put in stabile with the fuel too.

Did you blow compressed air thru the passages and use carb cleaner?

I highly recommend Berkebile 2+2 Gum Cutter. Nothing I've found works better for cleaning carbs.

Clean your fuel system (lines, tank, rebuild carb, replace fuel filter) and if that does my do it then check your points timing. But my money is on fuel system.

I just want to make sure I'm understanding this correctly as far as timeline, are you saying that the engine ran great, then the stalling incident occurred, and then immediately after it started having issues? That would indicate to me a relationship of direct causality between the stalling and the subsequent issues, and I would be skeptical of carb issues because I'm not sure how the engine stalling would cause the carb to suddenly clog. Or did the engine stall, run ok for a couple more days/weeks and then it started having issues?

It was running fine until the blades locked up. As soon as that happened thats when the engine started this issue.

If it happened just this way, I would check to see if the belts are still in all of the pulleys as they should be. Then check the timing.
