Timing must be off, my stock b3 will hold 85 mph with the trailer on behind, at 4500 ft
cold air across the desert..loaded with a honda rincon, 10x20 tent, 10 gallons each water , fuel and propane, BBQ, 4ft tub of camp gear, 4 ft full ice chest, 2 ft ice chest, back pack
This was the mexican desert with a cumins diesel, camper and trailer attempting
to take the festy..I got dibs on the camp site!
From all you have said, you are not getting 42 - 44 all in advance for what ever reason.
You have to have those numbers to make power and economy at freeway speed.
Most specs are given with base timing and that is okay as long as you get the top end
too. Maybe you have one of the advances stuck?
You might have to plan a little side trip to meet up with one of us that has the shop, tools, experience and know how for these kind of projects.Reflex paint by Langeman...Lifted...Tow Rig

Is your upper belt cover removed? If not, you need to remove it until you get these issues resolved. You have to remove the water pump pulley to do it. If you cut out the part of the cover that wraps around the tensioner you can get it off easier every time. Line up the marks on the cam at 12 and 3 o'clock. Look down at the bottom pulley about 1 o'clock. There should be a small notch (you might have to feel for it). It should be lined up with the 0 mark on the scale attached to the cover. If you can't find the notch on the pulley or there's no scale, there's supposed to be a mark on the lower cog that matches a mark on the case. On a carbed model, that is your cam and ignition timing mark (since they are timed to 0). You don't need to drive a thousand miles for someone to check this for you.

Good point. His cam timing could be off; instead of, or as well as, his ignition timing. Especially if it's running rich and is underpowered, that may imply cam timing is a tooth or two retarded, and not a carb issue per se. But I still say the ingition timing should be 7 degrees or more.Last edited by TominMO; 03-22-2012, 07:08 AM.90 Festy (Larry)--B6M (Matt D. modified B6 head), header, 5-speed, Capri XR2 front brakes, many other little mods

Read thru the entire thread. I know it's a low-miles Jap motor. But has the cylinder compression ever been checked?
Fuel: apparently not an issue here; but is fuel filter clean? Or maybe the rebuilt carb is not set up right.
Air: never really a problem unless your air filter is clogged
Spark: coil, disty, plug wires, plugs; check each plug for a cylinder-specific issue
Timing (cam): you claim it's been checked twice, so probably not an issue
Timing (ignition): without timing marks, how do you know it's at 10 BTDC?90 Festy (Larry)--B6M (Matt D. modified B6 head), header, 5-speed, Capri XR2 front brakes, many other little mods

I believe he have unusual 2000 -/+ yr B6 block imported from somewhere outside of USA with B6 1988-1989 head cylinder. The original head cylinder with JDM engine was different bolt pattern with exhaust and intake manifold so it possible not same crankshaft either. Also he used to have new Escort 1.6L carburettor out of NOS box but getting same mpg approx and poor running with idle.
