My 388 Fluxor bulldozer is acting funny. I checked the bypass valve and the alternator cap, but I just can't get it to run right. There is thick black smoke coming out of the coleston tubes on top but I don't know what's causing it. Do you think it might be the manifold output or the rosling gauge? I don't want to take the whole top block apart, help!
if your coleston tubes are getting clogged because you haven't been cleaning your manifold, it could cause similar problems. The thick black smoke might actually be oil. 387 Flǖxor (German) bulldozers had this problem about a couple of years ago. Just spray your manifold output with hydrogen peroxide, and check your rosling gauge after that. I think we can pretty much exclude the alternator cap here.
