HRT216SDA Throws belt NEED HELP PLEASE

[fotch]

I have a HONDA HARMONY II model HRT216SDA ser# MZCG-6035472 mower that throws belt over and over. I tried 2 new belts and neither will stay on mower once I pull the drive bar. It will pull itself about 2 or3 feet then throws the belt. The belt will stay on when just running the engine. I have a pic. of the mower bottom and maybe you can tell me if it looks right. The belt in the pic is a old belt which has been replaced

First, replace blade with new Honda OEM blade.

As far as the new blade can I buy the single blade or do I need to get the double blade setup like it has on it now? Also I cant find anything about adjusting belt tension in my owners manual or information online. I wrote Honda twice and got no answer. Thanks for taking time to answer me. Fotch

Belt throwing is nearly always caused by pulley mis-alignment. With the motion lever engaged, put a straight edge across the 2 pulleys to check for alignment. If a straight edge isn't possible a string stretched tight and a little skill will suffice as a straight edge.

I thought about the pully alingment before. One thing I noticed when pulling the forward bar, It moves the lever on top of the trans. then pulls just a little further which tilts the trans forward a little. This of coarse tilts the trans pulley forward a little. I thought this may be the problem so I ran the adjustment screw from loose to tight trying different positions and the pulley still tilts when pulling the go bar all the way. I was told there is suppose to be a stop you can buy that will stop the tilt but I cant find out who sells it. Anyone heard of that?? Should I try another new cable? Thanks Fotch

Honda Power Equipment HRT216 SDA TRANSMISSION (1) | CyclePartsNation Honda Parts Nation blades 3 & 15 in diagram are one & the same, blade 4 is used along with blade 3 for mulching. In the transmission diagram I posted above bolt 5 is used to adjust belt tension. If you are not mulching, a new blade 3 will be ok to use. Be sure to inspect all parts including pulley in this diagram for wear & torque blade bolts to Honda specs.

I found in another forum that my model mower has the problem of throwing the belt and you can buy a part honda made for belt throwing. Honda has a $15 stopper kit 06915-VG4-305 that includes a stopper collar (a new part) and three washers. I ordered it tonight I will let yall know if it stops my problem. I also found that honda has a recall for the HRT216 SDA fuel tank. They replace it for free. Mine leaks so we'll see what they do for me. FOTCH

I got my belt throwing problem stopped by using the $15 stopper kit 06915-VG4-305 . I seem to have come up with another problem. My engine seems to only come up to half speed when I push the lever all the way up. I have a new carburetor installed so I dont think its that. I traced and lubricated the throttle cable and it goes as far as the fittings allow. I tried adjusting the cable and it didn't help. At full throttle it runs slow and when I pull the lever back to the slow end it cuts off when it is only half way back. The engine will rev up when I push the governor arm. What should I look for now? Thanks Fotch
