Tecate Help Please!

[JMiller]

What will cause my engine to foul sparkplugs under a load? My motor is rebuilt and so is the carb. It just started doing this all of a sudden before I rebuilt it.Please help. Any comments and help is appreciated. :(

ignition system, wrong plug, bad carb setting, clogged pipe, dirty air filter, low compression, bad seals

Clogged Pipe?

[Tyler 54]

Yes, Years of 2 Stroke oils, smoke All kinds of crud gets clogged up in the pipe. I had a polaris that did this once. I was told by the local polaris mechanic to BURN it out. LOL I fileld the piep full of solvent, gas and a few other chemicals, then Repeatedly blew it out with my torch, WOW was that a big flame. anyway After I got it all burnt out, it ran liek a top again.

my 2 cents, Tyler

The pipe or the silencer? Is there any way to tell if its clogged?

[Tri-Z Pilot]

Probably the pipe, you could try running it without the silencer, and see if that helps, or you could take your pipe off and look/blow through it I guess.

It's the pipe it self. It was kewl, It was like a giant flame thrwoing torch. It took forever to do.

My pipe and silencer are clear.

Welp, I gues ssince you can't get it running. I guess you can give it to me, I would pay for half of the shipping cost to get it here :-D LOL j/k

Have you tired a Hotter burning plug?

[JMiller]

I think I got it running. I switched the carb minus jets from my 84 KXT. I think it'll run now. I'll let you know.
