  1. The engine bog tells me that the motor is ok...that's the motor drawing lots of amps to get started. Could be the flow/pressure/vacuum switch (depending on which your machine uses) or the thermostat/high limit switch...could be the transformer...maybe a bad fuel pump or stripped coupling in the burner. Call me if you like, and I'll try to talk you through a few tests.


  2. Would a wagner paint crew 770 work well for this, or something else.

    Do NOT buy a Paint Crew. I service Wagner products, and this is the one I've seen the most problems with. The Apex 1620 is a good unit. Most of the time when I see one of those, it's operator error...usually improper cleaning. I've got a refurbished 1620 for sale. Lowe's gets $425.00 for it new, I'll take $275.00 and give you a 90 day warranty.


  3. Could be the motor or the solenoid. The solenoid serves 2 purposes...engage the bendix into the flywheel and make connection for the starter motor. The first thing I would do would be to hook the positive cable directly to the power lead in to the motor and see if it spins. If it does...motor fine, solenoid not. If it doesn't...motor bad, solenoid still in question, although probably good.


  4. i found this pic on some forum a little while back....is this sufficient spacing between the machine and the piping? in your opinion is my dealer trying to rip me off telling me that it costs $130 just for the adapter. What the tape covers up is the 'hack job' cutting that he did to get it to form around the coil. he taped it because he probably used regular scissors to cut the metal! No sheet metal screws either...just tape holding that in place...If there are any ALKOTA dealers on this site please pipe in. i can't believe that Alkota would not offer an adapter for their machines. I will be visiting an HVAC place on monday to get his exhaust done right. Thanks for your advice guys.....keep it coming.

    Yes, that is a perfect example of the spacing needed.

    Seems to me, too, that part of your exhaust port is covered with sheet metal, further blocking the flow.

    None of the machine manufacturers offer exhaust adapters that I know of.


  5. Looks like a register boot for a HVAC system...it will not last long exposed to high stack temps. I also do not like the fact that it is sealed to the machine...you need an air gap between the collector and the machine for make up air to promote proper drafting, or the coil will soot up. A burner fan is designed to push enough air for proper combustion...it is not there to push spent exhaust gasses up a stack. I have custom collectors made in a HVAC sheet metal shop out of heavy gauge metal. A good one will run you around the $130.00 you paid for that. Check your local Yellow Pages for HVAC supply houses and call and see if they do "in house" fabrication. They'll help you with the design and everything.


  6. Down here I cannot find sand but they have soda or Black Beauty (copper slag) and it is about $6.00 per 50 pound bag. I am wondering if you had a bigger air compressor if it would be more cost effective to just sand blast it or is it still less expensive to water sand blast it?

    Black Beauty is actually the stuff I was using. It's as sharp as silica, but cheaper. I would imagine a really huge job might go a little faster with an industrial compressor and sand pot, but you've got to be hooded, sutied, gloved, and wear breathing protection. Wet sandblasting requires a good pair of closed sided goggles. I also recommend a hat to keep some of the sand out of your hair.
