I plan to check the compression after a little more carb tuning fails. Any insight would be greatly appreciated, I have little time to work on it and would love to start enjoying it.
Before selling it, see if you can find a local shop to look at it for you. It may be something that you just don't see. Set a dollar amount to diagnose. Maybe Someone here can help or help to recommend a shop near you. Throw out a Zip-code to narrow it down.

Re: 72/68 blazer 4x4 dream/nightmare

That has crossed my mind, my buddies and I always work on our own stuff and have never had the need for a shop. There's so many possibilities the shop hours would rack up fast. But if anyone knows of a reputable shop near 48185 I'm open minded at this point.

Re: 72/68 blazer 4x4 dream/nightmare

I pulled the carb spacer off, that must have sealed a minor vacuum leak. It idles much better and a little more responsive, baby steps. It's also nice having a taller garage and being able to walk under the hard top now.

Re: 72/68 blazer 4x4 dream/nightmare

Agree with a shop visit - sometimes the money spent is worth it to to have the problem diagnosed and then you can fix it.

Also - having the issue fixed would potentially net you more money in a sale.

Re: 72/68 blazer 4x4 dream/nightmare

So I was offered full asking price the other day and decided to keep it. I told the guy he'd get the first call if I changed my mind again. Anyway after solving the vacuum issue I played with the initial timing a bit last night. I found that 12* made a little more improvement. Better response, more power while cruising and the run on wasn't constant. I still need to set the total timing as soon as a get a good dial back timing light and a helping foot. After 2 harbor freight lights I guess I'll stop being cheap. I've never messed with curving a distributor, I'm sure it'll be a few long aggravating trial and error days. I'm really eager to get it looking right after making it act right.

Re: 72/68 blazer 4x4 dream/nightmare

It's hard to get rid of something you've worked so much on. With a clocked rv cam and high lift rockers mine likes to sit around 12-15 btdc as well to get full power. I don't use the timing tab anymore though. I timed mine with a vacuum guage and timed it for best overall vacuum at 3000 rpm. Made a world of difference in power.

Re: 72/68 blazer 4x4 dream/nightmare

I kind of suspected the tv setting for the Trans as a big portion of the problem, even though I set it as directed. I had a Trans shop reset it with the pressure gauge hooked up, they even had a hard time he said. It made a huge difference, firmer shifts, better response. It still falls off a bit after 3rd but no rediculous. Testing passing gear I found a new problem, I got in it in 3rd downshift was fine up shift seemed pretty hard then the truck started bouncing. It was like driving over a washboard at 40mph, almost like there were no shocks in the front. I'm really hoping it's not a torque converter issue, I'd think that would be more of a jitter. I stopped to inspect it and didn't see anything, it hasn't done it again but I haven't gotten into it either since.

I also like the idea of restoring the other frame while driving my truck.

Do you still have access to that 2wd frame? In Michigan ?
Thanks

How clean is that frame? I'm still thinking of building a rolling chassis while driving the truck. I just haven't found anything as clean as mine yet.
