maybe muffler blew packing out and is clogged a bit? dunno, but if it runs well with the cat off something is not right there, either running really rich and combusting in the exhaust or a restriction somewhere causing heat to build up.

 

I just got my TII running with my Hayes motor and my Cat was glowing after we finally got it going. As it turns out, the water thermo sensor is bad. At 68 degrees ferenheit, the thermo sensor is supposed to read 240 ohms, mine is 1.85 K. This condition causes the EGI control to think that the temperature is -10 F and therfore cranks up the fuel to compensate. The exess fuel runs through the engine, into the exhaust and then burn in the exhaust. Causing the exhaust to glow red.



Check your thermo sensor. It is located behind the alternator on the water neck. It has a plug similar to a fuel injector. Your FSM should tell you how to check it.



Hope this helps you.

 

cool i'll check that sensor out then. but i took a broom handle to my cat converter so now its just a hollow pipe that looks like a converter. i hooked everything back up last night and tried to start it but it wouldnt go. it gave all the signs of it being flooded so i did the 3 step unflooding bit like 12 times and still no luck. it got close the last few times. i was thinking i could try the long unflood method today some time. but im wondering if its going to be to rich for my mixture now that all the preasure is gone, and how do i adjust it back down.

 

well i realized once i got out to the car i dont even have a thermo sensor on my model, oh well. anyway i tried some starting fluid and that was a no go. then i decided to push start it. it tried but no go. then i decided to do the complex unflood method. did it and no go, not even a try. my friend knows for a fact that there is spark at the end of the lines but dosent think its going through the plugs. bad plugs mabey. then i decided id go for new plugs so i pulled a top one and a bottom one for refrence when getting my new ones. the tips of them were soaked in fuel after only the 5 seconds i tried to crank it. do you think its just really really flooded or are the plugs bad? when i did the complex un-flood it smelled like fuel but there was no smoke or fumes visiable and i did not notice anything that had been pushed out of the plug holes. im stumped here.
