    36 or 48 volts?

    I'm building a kart out of a lawn tractor. Using the 6 speed transmission. I only need it to go walking speed , but with enough TQ to make it up a 25* or so incline for 1000 feet. The transmission is 9-1 in 6th gear and 30-1 in 1st. The batteries are 12v 20ahr each

    36 or 48 volts?

    What would be better? Power wise and time? I am looking at 2 motors. 1000w at 36 amps 36 volts or 1000w 27 amps 48 volts?

    Gearing question, tell me what you think please?

    I picked up a lawn tractor today and am starting to build a kart to drive down to my beach and back. Down hill around 25-30*. Here is what my gearing came out to. Can you tell me if the motor I want will work? I need the Tq to go up the hill. Looking at 750w 36V to drive this. So motor to...

    need help picking a motor.

    Thanks. I have a set of 15x10 and 13x8 turf tires for now off my tractor. I need to know what kind of motor will power the weight. Will I need 1 motor for each tire? If I run a true posi the steering is terrible. My go kart has a posi and the turning stinks. Maybe find a transaxle? Also would...

    need help picking a motor.

    Hey guys. Here's my deal. I just bought a house. Accross the street we have a private beach. My family and I love to go down there during the summer. My brother-in-law has MS and has a hard time walking down the long road to get to it. When he gets there he can't even walk on the sand. I want to...

    Got new engine Subaru EX27

    Why is 200watts not enough? 200w puts out 16.6 amps. (2) 55watt bulbs need 9.1 amps to run. 200w are plenty for 2. The engine I have has a rectifier and a 15watt charging system. Does yours have electric start? The electric starts come with it. The blue wires do go to the rectifier on mine. The...

    Got new engine Subaru EX27

    Yes it will. I hooked up the lights I want to use to a spare lawn tractor battery just before for a test. I had it on trickle charge for a couple of days so the volts were at 12.09. The lights I'm using are (2) 55 watt fog lights. I hooked it up to the battery with a VOM and watched to see how...

    Got new engine Subaru EX27

    I just bought a 7Hp robin. The 2 yellow wires on mine are for a low oil light. It looks like yours are comming off a rectifier. The rectifiers are used for 15 and 40 watt alternators. 15w is only like 1.5amps enough to charge a battery. The 40 is only 3.3 still not enough. Mine only puts out the...

    How much keyway do I need?

    Thanks guys. How much is a BIT??? 1/2" or less? 3/4" would make me happy, but thats not going to happen. I just looked up the specs on a Tecumseh 6HP OHH60-71216E and the shaft is 2 9/16. The shaft I have is measuring at 2 6/16. Thats 1/4" shorter....:furious2:

    How much keyway do I need?

    I installed my Torque-a-verter TAV2 on a Robin EX21 engine. I noticed the outert hub on the crank shaft only slides on a little less than a 1/2 inch. I could machine it down .70 and it would give me exactly 1/2 inch if I needed. How much is good or not good? This part is the part...

    Anyone put a 9 tooth on a TAV 2?

    What kind of performance gain did you get? I just took apart my TAV2 for the new engine and the gears look real pointy. I'm guessing thats a sign of wear.

    Engine with alternator?

    The 13hp won't work with tha TAV I have. How do you make one? I would like it to just hook up to a batt and charge.

    Engine with alternator?

    Thanks. This stinks though. I was leaning to the second one and spending the extra cash. It also has a easy hookup for the throttle too. The more researching I do I'm finding out it's not made anymore and I can't find a similar engine:furious2:
