Idasho Posted June 19, 2011 Share Posted June 19, 2011 The previous owner of my '84GL Ive been chasing carb problems for a while now. Finally decided to fall in line with the rest of the crew and pony up for a Weber. I found this while tearing it down in prep for the new carb. The Hitachi looked like it had been rebuilt recently. I think the guy must have used a wood chisel and hammer to remove the old gasket material The lower gasket on the phenolic spacer wasnt sealing very well. Shhhh....... dont tell the wife. She thinks the Hitachi carb was totally shot Link to comment Share on other sites More sharing options...

Idasho Posted June 19, 2011 Author Share Posted June 19, 2011 Definitely the worst mating surface Ive ever had to deal with. I spent 20 minutes or so sanding it out with a block and paper. Looking much better, but I think I will have to do some JB weld filling, then sand it out again Link to comment Share on other sites More sharing options...

El Presidente Posted June 20, 2011 Share Posted June 20, 2011 ************ JB weld.use Allmetal,it sands and finishes much better. cheers, b How does Allmetal hold up to gasoline? I've been unimpressed with JB weld for carb repairs/mods that are in direct contact. Idasho: Looks good! Link to comment Share on other sites More sharing options...
monstaru Posted June 20, 2011 Share Posted June 20, 2011 How does Allmetal hold up to gasoline? I've been unimpressed with JB weld for carb repairs/mods that are in direct contact. Idasho: Looks good! it has held up to everything i have thrown at it so far, including gasoline, diesel,and brake fluid and brakleen... fixed the base of a 32/36 with it, never had issues.buddy fixed an injector boss on a marine diesel with it,no issues.I fixed a broken bleeder screw with it,no problems. is it designed for all of that?i dunno.but it has been used and abused thats for sure.i would say that the mixture is obviousluy the most important.getting the amounts proper is very important not only for set time, but also strength. it did not hold up to muriatic acid when i was trying to use it to fix a ding in 1911 frame.but i did not really expect it to:grin:......it just kinda dissolved off chunkily....... anyways.cheers, b Link to comment Share on other sites More sharing options...
brumby420 Posted June 20, 2011 Share Posted June 20, 2011 Well i hope jb weld holds up well because im soon going to be attempting to fix the hole in my transmission case on my tt350 dirtbike. Link to comment Share on other sites More sharing options...
Caboobaroo Posted June 21, 2011 Share Posted June 21, 2011 I used JB Weld to put a brass fitting into the aluminum water cross over passage on my N/A XT spider intake a few years ago. I applied it with a toothpick so I could get an even amount around the base of the fitting, put it under the heater in a spare room for 24 hours and never had an issue. Its passed hands a couple times since I sold it and to my knowledge, it still working. If its prepped correctly and applied correctly, you can do quite a bit with it. I've also used JB Weld to fix pitted caliper piston bores on a '68 Buick as they were heavily pitted from corrosion. Link to comment Share on other sites More sharing options...
